How
Databases Changed the World
Explore the amazing history of the
database industry. Tune in to this Webcast from The Computer
History Museum and hear stories from pioneering database leaders,
including Oracle's
''Dr. DBA'' Ken Jacobs. Oracle's
Ken Jacobs Discusses How Databases Changed The World
Dr. DBA joins distinguished panel at
Computer History Museum event
(2 hrs.)
|
Ken Jacobs,
Oracle vice president of product strategy for server technologies,
participated in a panel discussion, "How Databases Changed the World" at
the
Computer History Museum.
Jacobs, a
22-year Oracle veteran known as "Dr. DBA", was joined by luminaries from
Sybase, Informix, Ingres, Illustra, and IBM.
Panelists
discussed how databases have changed the face of business, as well as
key milestones, obstacles, and lessons learned.
Can you
imagine a world without databases? Every time you withdraw cash from an
ATM, make airline reservations, or charge something on your credit card,
database systems are working behind the scenes. Since the dawning of the
relational database model in 1970, and since the introduction of Oracle
as the first commercial relational database system in 1979, database
technology has evolved rapidly and now is essential to just about all
transaction processing and business intelligence applications.
As part
of continuing efforts to preserve industry history, the Computer History
Museum hosted a panel discussion, "How Databases Changed the World,"
gathering database luminaries to reflect on the past and ponder the
future. Panelists discussed how the database industry got started and
how it has changed business, with some key milestones, obstacles, and
lessons learned along the way.
Panelists
include Oracle's Ken Jacobs, who has held a number of technical and
management roles for Oracle since helping to establish the first Oracle
office in Washington, DC in 1981. He's worked in consulting, support,
product management, and product marketing. Ken has helped guide the
development of the Oracle database product over the years, and has been
an advocate inside the company for customers' interests.
Other
panelists include: Chris Date, a well-known author whose books have
popularized relational database technology; Herb Edelstein, independent
consultant and author; Bob Epstein, the founder of Sybase; Pat Selinger,
who contributed to IBM's original relational research and who now heads
DB2 architecture and technology; Roger Sippl, the founder of Informix;
Michael Stonebreaker, former UC Berkeley professor (now at MIT), and
architect of Ingres and Postgres; and moderator George Schussel, the
founder of DCI, a technology conference and expo company.
Edgar
Codd, database theorist, dies at 79
By Katie

Edgar F. Codd, a
mathematician and computer scientist who laid the theoretical foundation
for relational databases--the standard method by which information is
organized in and retrieved from computers--died on Friday at his home in
Williams Island, Fla. He was 79.
The cause was heart failure, said his
wife, Sharon B. Codd.
Computers can store vast amounts of
data. But before Codd's work found its way
into commercial products,
electronic databases were "completely ad hoc and higgledy-piggledy,"
said Chris Date, a database expert and former business partner of
Codd's, who was known as Ted.
Codd's
idea, based on mathematical set theory, was to store data in
cross-referenced tables, allowing the information to be presented in
multiple permutations. For instance, a user could ask the computer for a
list of all baseball players from both the National League and the
American League with batting averages over .300.
Relational databases now lie at the
heart of systems ranging from hospitals' patient records to airline
flights and schedules.
While working as a researcher at the
IBM San Jose Research Laboratory in the 1960s and '70s,
Codd wrote several papers outlining his
ideas. To his frustration, IBM largely ignored his work, as the company
was investing heavily at the time in commercializing a different type of
database system.
"His approach was not, shall we say,
welcomed with open arms at IBM," said Harwood
Kolsky, a physicist who worked with Codd
at IBM in the 1950s and '60s. "It was a revolutionary approach."
It
was not until 1978 that Frank T. Cary, then chairman and chief executive
of IBM, ordered the company to build a product based on
Codd's ideas. But IBM was beaten to the
market by Lawrence J. Ellison, a Silicon Valley entrepreneur, who used
Codd's papers as the basis of a product
around which he built a start-up company that has since become Oracle.
"The sad thing is that Ted never became
rich out of his idea," Date said. "Other people did, but not Ted."
Edgar Frank Codd
was born the youngest of seven children in Portland Bill, in Dorset,
England, in 1923. His father was a leather manufacturer, his mother a
schoolteacher.
He attended Oxford University on a full
scholarship, studying mathematics and chemistry. During World War II, he
was a pilot with the Royal Air Force. In 1948 he moved to New York and,
hearing that IBM was hiring mathematicians, obtained a job there as a
researcher.
A few years later, in 1953, angered by
Sen. Joseph R. McCarthy's pursuit of Americans that he said had
Communist ties or sympathies, Codd moved to
Ottawa for several years.
After returning to the United States,
he began graduate studies at the University of Michigan at Ann Arbor,
where he received his doctorate in computer science in 1965. In 1967, he
moved to California to work in the IBM San Jose Research Laboratory.
He and his first wife, Elizabeth, were
divorced in 1978. In 1990, Codd married
Sharon Weinberg, a mathematician and IBM colleague.
In 1981, he received the
A. M.
Turing Award the highest honor in the computer science field.
Codd
is survived by his wife of Williams Island; a daughter, Katherine
Codd Clark of Palo Alto, Calif.; three sons,
Ronald of Alamo, Calif., Frank of Castro Valley, Calif., and David of
Boca Raton, Fla.; and six grandchildren.
